[PATCH 0/2] alpha: fix build failure

[Sudip Mukherjee]

We were getting build failure on allmodconfig. Mainly two causes
ioremap_uc was not defined and __delay was not exported.

[PATCH 2/2] alpha: lib: export __delay

[Sudip Mukherjee]

__delay was not exported as a result while building with allmodconfig we
were getting build error of undefined symbol. __delay is being used by:
drivers/net/phy/mdio-octeon.c

I already submitted patches to fix those problems some 6+ weeks ago.
Hope you'll have more luck.

I have both of these patches queued for 4.3.  Cc'ing me is a way of
preventing stuff from falling through cracks..

But I didn't tag these patches for -stable backport.  Should I have
done so?  If 4.2 is busted on alpha then I guess "yes".

No, this only affects 4.3-rc1 and -next.

For my allmodconfig test with next-20150915 alpha, m32r and openrisc
failed. And ofcourse mn10300 is broken since many months now.
Have you already done something with m32r or should I try? If both of us
are trying the same it will be a wastage of time. So asking you.

I am not building m32r:allmodconfig or openrisc:allmodconfig.

You can always check http://server.roeck-us.net:8010/builders to see
what is covered by my builds and tests.
